Abstract:
When the compressible multi-material flows ar enumerically simulated, much trouble is made from two different state equations. The Ghost Fluid method is used to avoid the problem. The shock tube problem containing two ideal gases with different specific heat ratios is simulated by using discontinuous Galerk in finite element method and Level Set method. The numerical results are in very good agreement with the exact solution. In addition, the gas-water shock tube problem, air in-teracting with helium bubbles and air interacting with R22 are also simulated. The conclusions are consistent with the relative references. The results show that the method used for compressible multi-material flow is feasible.
